There are signal beads that remove noise of general signal lines, power beads that remove noise of power lines, GHz beads that remove noise in the GHz band, and CMF (Common Mode Filter) that removes common mode noise at the differential mode communication side (USB, HDMI, and CAN communication).

Bead

Beads are surface-mounting–type parts made by using the multilayer process. These are passive components that remove noise by using the characteristics of ferrite. We have a lineup of products that can remove noise in the band ranging from 5 MHz to GHz using the characteristics and magnetic permeability of various materials. These are mainly used for removing electromagnetic noise of mobile devices and digital A/V equipment.

General Features

Features of Products (Technology)

Covers the noise in a wide-frequency band because the magnetic permeability of diverse materials has been developed and applied.

The smaller the products become, the more difficult it is to equip them with high-impedance characteristics in high frequency. By developing technologies that can resolve stress between the body and the coil of the small-size product, high-impedance characteristics in high frequency is made possible.
